Growstone Hydroponic Growth Mediums and Super Soil Aerators are a horticultural, scientific and environmental win-win-win. Growstones are an effective alternative to perlite and Hydroton®. They guarantee a considerably higher aeration and faster drainage than perlite, while simultaneously holding more water than Hydroton. Growstones provide: Other Growstones characteristics are: 3 times more water than Hydroton® High porosity and aeration Over 70% more aeration than perlite Proven yields ‘as-good-as’ the industry standards 4 times more aeration than coco coir Can satisfy a wide range of plant requirements for different growing systems and climates Made from 100% recycled glass The perfect balance of air and water Not strip-mined like Hydroton® and perlite Growstones highly porous media associate a good water holding Inert capacity to high air-filled porosity. At field capacity, Growstones pH neutral after preparation hold 30% water within its pores and 50% air by volume within its 100% non-toxic and chemical free inner and inter aggregate spaces. This water to air ratio maximizes Lightweight, dust-free water availability and aeration to your plant roots. It also Impossible to over water facilitates drainage making it impossible to over irrigate.
